Introduction: Nowadays, mobile phones in the market have a variety of mobile power sources, and consumers lack professional knowledge, so consumers often choose mobile phones that do not have good reputation. According to the regulations of the government market, mobile phone power supply products need to have strict regulations. Here are some details to look at when purchasing mobile phone power supplies.
First, check the rated output of mobile power
The rated output includes voltage output and current output. Since different brands of mobile phones have different input voltages and currents, the mobile phone's rated output range is limited. The rated output is best matched to the phone's rated input to protect the phone from over-voltage. Although the larger the rated output range, the more mobile phones that can be applied, the more cost-effective. However, many mobile phone power sources are blindly pursuing the scope of application, often neglecting circuit protection design, poor technology, and poor use of materials, causing standard output to become a dummy.
Second, check the capacity of mobile power
The capacity is expressed in terms of MAH (milliampere-hours) or WH (watt-hours). The conversion rule is AH*voltage=WH, 1AH=1000MAH. If the applicable digital device's battery is 700MAH, a mobile power source with a capacity of 2200MAH can be charged 2-3 times. The higher the mobile phone's mobile power capacity, the more times it can be charged. The capacity is not as big as possible. First, a lot of mobile power capacity seems to be very large, mostly false publicity by the informal manufacturers, and the actual output cannot reach. Second, security requirements are higher.

Third, check the use of mobile power
The number of recyclable batteries described on the mobile power supply product box can still maintain about 80% of the power, and the number of cycles for Wopin mobile power can reach more than 500 times, which means the life of the mobile power supply. The lifespan of mobile power is related to the battery. At present, except for the inferior batteries, the difference between different brands is not significant. The mobile power supply for mobile phones is considered to be fully flushed twice a week to ensure that the effective time is up to 5 years.
A clear view of the rated output, capacity, and frequency of use of the mobile power supply is critical to our future use and is very representative. Second, when buying, we must also consider the size and weight of the power supply. We hope that consumers can focus on understanding the details of mobile phone power supply purchases and select high-quality mobile phone power supplies that meet their requirements.
